I have the prostaff 3-9x50 and 4-12x40 both with the bdc ret and also a monarch ucc 6-20x44 and had a 6-24x50 monarch 3
For value for money the prostaff are fantastic with very good glass, fixed parallax , I have these on my rimmies as the ret is very handy for a loopy .22,
I sold my Monrach3 as the UCC has much better glass imo ( I know everyones eyes are different but to me the ucc is much sharper, this has front ao as opposed to the side parallax of the monarc3) One thing I have found is they are very good quality , everything works and moves nicely
what rifle are you thinking of putting it on ?
